WIRE-.STRETCHING TOOL'.

Application filed January 3, 1922. Serial No. 526,806.

ed certain new and useful Improvements in a Wire-Stretching Tool., of which the'following is a specification.

My invention relates to wire stretching tools and is designed particularly to enable wire screen, screen cloth or other like. inaterial to be fastened onto frames, easements or the like and the material stretched while it is applied. l.

This invention is distinguished by itsY simplicity and eliiciency, it being cheap to manufacture and particularly adaptable to the use for which it is designed.

In brief my inventioncomprises a metal or wood handle into the working end of which are set a plurality of metal studs arranged in a plane with the axis of the handle, these studs being of graduated length, with the shortest of the studs at one end and the longest at the other. The length of the studs increases by a constant quantity, which feature is of particular advantage as will be explained more fully hereinafter.

and the many advantages thereof will be made more apparent in the accompanying specification and drawings in which:

Fig. l is a perspective view of my mproved tool in the operation of stretching the wire screen,

Fig. 2 is a similar view with the tool shown in a different position,

Fig. 3 is a side elevation of the tool, Fig. 4 is a side elevation as viewed from the left in Fig. 3, and

Fig. 5 is a bottom plan view. l Referring now more particularly to the drawings it will be seen that the tool consists of a handle 10 which may be of wood, metal or any suitable material and is formed with what will be termed a head 11. Projecting from this head l1 in a plane with the aXis of the handle is a plurality of metal studs or pins 12. The projecting lends of these studs are beveled on eachside to form chisel edges 13. It should furthermore be noted that these studs are of' graduated lengths, the shortest stud being to the left as viewed in Fig. 3, the length thereof increasing by a constant quantity toward the The manner in which my device is usedl right, the chisel edges beinginclined paralle-l to a line drawn from the shortest stud tothe longest stud. t should furthermore be notedthat thestuds are disposed one behind the other -in a single plane.

of'operation there Vis illustrated for example clearly illustrated.

For the purpose of describingthe method `a frame ,14 uponwhich there is to be fastened ascreencloth l5. rlhe screenv cloth 4is first tacked along two of its'edges as Thereupon, cemmene-vv ing at the corner foi'inedby a'fast'ened and an.v unfastened yedge the tool is linserted `through the screen "cloth and into the material of the frame or casing towhich the trated in Fig. 1, and with the planev of the screen clothl is to be fastened. The tool'y studs parallel to the edge about to be rfas-"- tened.` lThe axis of the handle is inclined toward the `corner of the two fastened edges.

That is, the handle is at an acute angle with the plane'of the screen cloth aslaid upon the frame and is inclined towards the corner A of the frame (see Fig. 1). y

As has heretofore beenstated, the studs have passed through the screen l"cloth and are engaged with their chisel edges into the frame. to the vertical position relatively to the plane of the screen cloth as laidupon the The handle of the tool is then raised.

frame, by which operation the studs engage the meshes of thel screen cloth through which they have been inserted kand ystretch they screen cloth awayfrom both edges andhold the same taut whereupon the screen is tacked or fastened to the frame as far as the same is stretched by this first operation. `The position of the tool after it has been raised to a vertical positionis illustrated in Fig. 2.

The tool is then disengaged and re-inserted .i

progressively along this unfastened edge andl frame, stretches the screen cloth lengthwise.

Furthermore, the studs will be caused to successively disengage the kscreen cloth as the handle is moved in a direction corresponding to the length of the frame, that is,"
